If you cannot make prints as you want because of paper type, paper size, or paper capacity problems, use recommended paper. See "Recommended Paper Sizes and Types", About This Machine.
Curled paper causes misfeeds, soiled paper edges, or slipped positions while performing staple or stack printing. When using curled paper, first straighten the curl with your hands or by placing the paper upside down. Also, lay paper on a flat surface to prevent paper from curling, and do not lean it against the wall.
